Function Families
Cubic Function
Quartic Function
Power Function
Logarithmic Function
Logistic Function
Trigonometric Function

For each of the function families above, the graphing calculator will calculate a regression equation.  To access these regression equations, press calculator STAT button right arrow button imageon your graphing calculator.  You will see this screen:

This image displays a calculator screen under the Stat Calc command on the calculator. The screen shows Option 1: One variable statistics, Option 2: two variables statistics, Option 3: the median-median line, Option 4: linear regression of a x plus b, Option 5: quadratic regression, Option 6: cubic regression, and Option 7: quartic regression.

The numbers or letters in the list correspond to the following regression equations:

4:  Linear Regression
5:  Quadratic Regression
6:  Cubic Regression
7:  Quartic Regression
9:  Logarithmic Regression
0:  Exponential Regression
A: Power Regression
B:  Logistic Regression
C:  Sinusoidal Regression (Trigonometric Function)

Khalid decides to try the cubic function model.
